110v outlet

Hi guys. New to posting but I have been lurking for years. I am going to try this area as well. I see that many of the newer 220v welders have a 110v outlet installed on them for coolers or grinders or whatever. How is this accomplished? I have looked at my Square wave 175 and there is no neutral wire. I would like to add a 110v outlet but I don't see an easy way. Thanks!

A 220 is two 110 "legs" feed in.... not really a big deal..... using a multi meter connect your leads (from the meter) one to the center and one to the right / left prong of the receptacle and you will see 110 on each one..... just remember if you are welding and your buddy plugs up the grinder you will trip the breaker as the draw is on one breaker....plus (unless you add it) the 110 rep. wont have a fault protection and could let some magic smoke out

To accomplish this their is a neutral in the machine which is what gets you the 110. So that means it's a 4 or 5(3 phase or single phase) wire setup,2 hots 1 neutral & ground or 3 hots 1 neutral & ground.

I'm not an electrician, but isn't it pretty standard to have the neutral and the ground tied together in the box? I don't see how it makes a difference.

I'm not contradicting, I'm asking for clarification.

It makes a huge difference. Neutral and ground are not the same thing,ground is for safety neutral is return to point of distribution. When you tie neutral to ground you potentially energize the machines chassis back on the ground and could knock yourself or someone else on their ass.

It is very important that they are tied together in one and only one location, the main service entrance. It is illegal and dangerous to tie them together in other locations. Older dryers and ranges with 3-prong plugs used to do this, as a cost saving measure, but that, too, was done away with long ago, and now they are four wires, even though two of them might go to the same bar in the panel.

You're mistaken neutral and ground don't terminate at the service. Neutral comes from the utility company and ground is supplied by Earth(driven stake) or the water main(clamp). I also forgot building steel by cadweld or drill & tap.
